DEEP-WELL-PUMI" CONNECTING DEVICE.

Application filed July is, 1925; .seriaiNo. 44,027.

My invention relates to connecting devices adapted to connect upper andlower working barrels in deep well pumps.

It is the object of my invention to provide improvements for the deepwell pump rel, and with external threads to support the lower workingbarrel casing, and to further provide a separable coupling memberadapted to form a seat for a relief valve,-

with a spider formation adapted to admit liquid from the annularaperture between the lower working barrel casing and the lower workingbarrel into the upper barrel and to secure the lower working barrel tothis coupling member. It is specifically my object to support thiscoupling member by exterior threads engaging threads on the inner sideof the lower working barrel casing, which may conveniently be extensionsof the interior threads of the lower work ing barrel casing by which thelower work-. ing barrel casing is supported from the bushing. v

It is my purpose to provide with this novel construction for independentadjustable elements which permit longitudinal adjustment of theseparable coupling within the lower working barrel casing so that thestroke of the lower plunger of a deep well pump may be regulated withregard to the relief valve with desired accuracy. I have a furtherobject of so reinforcing the support for the lower barrel that there isno tendency for the supporting piece or spider to be broken ofi.

Referring to the drawing in which I have illustrated a preferredembodiment of my invention:

Figure 1 is a longitudinal vertical section of a deep well pumpassembly.-

Figure 2 is a horizontal section taken along the lines 22 in Figure 1.

Generally indicated at 1 is the upper barrel of the structure. externalthreads recessed as at 3 supports the lower working barrel casing 4. Theshaft bushing with internal threads adapted to support the upper bar- Abushing 2 with its the indicated at carries the per sucker piston 6within the upper barrel and the lower piston 7 within the lower workingbarrel. Arrelief valve 8 through which the shaft extends is supported ona housing 9 which is wedged with a taper fit within the separablecoupling member 10. The separable coupling member is thread edthroughout its outer periphery and the threads with which the lowerbarrel casing- 1s supported by the bushing are extended be adjusted to adesired position within the lower barrel casing. Below the taperedportion of the separable coupling, internal The grooves discharge intothe upper barrel through orifices or ports as indicated at 16 inthewalls of the separable coupling. i The particularly useful results ofmy new structure as indicatedin the foregoing statement of my objects,will be readily understood when it is considered that the bushingmember, which in known structures has been usually extended forming anintegral as at 11 so that the separable coupling. may

piece with the'webbed portion and the portion forming the seat for therelief valve is in my new structure entirely independent. The separablecoupling not only supports the lower working barrel much more rigidly,but by turnin the separable coupling further, down wit in the threads ofthe lower working barrel". casing, any desired 1 degree of clearancebetween the lower piston and the relief valve may be obtained.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. In a deep well pump, an upper barrel, a lower barrel casing, a lowerworking barrel within the lower barrel casing, a housing between theupper barrel and the lower working barrel, a bushing for connecting thelower barrel casing with the'upper barrel, and an independent membermounted within the lower barrel casing supporting the lower workingbarrel and the housing..

2. In a deep well pump, an upper barrel, a lower barrel casing, a lowerworking barrel within the lower barrel easing, a housing between theupper barrel and the lower working barreh a bushing for supporting thelower barrel oasing from the upper barrel, and adjustable means forretaining the lower working barrel and the housing independent of thebushing.

3. In a deep well pump, an upper barrel,

a lower barrel casing, a lower working barrel within the lower barrelcasing, a housing between the upper barrel and the lower working barrel,a bushing for supporting the lower barrel casing from the upper barrel,and adjustable means for retaining the lower working barrel andthehousing'independent of the bushing, said means provided with recessesand ports and mounted in threads within the walls of the lower barrel 20easing.
